Weather-resistant high-strength environment-friendly antique-imitation brick and preparation method thereof

Abstract

The invention discloses a weather-resistant high-strength environment-friendly antique-imitation brick. The weather-resistant high-strength environment-friendly antique-imitation brick is prepared from the following raw materials in parts by weight: 10-20 parts of blue stone powder, 3-7 parts of antique-imitation auxiliaries, 7-9 parts of blast-furnace slag, 5-7 parts of steel slag, 4-8 parts of coal gangue, 10-14 parts of purified landfill, 8-12 parts of waterproof latex, 6-8 parts of tackifying additives, 13-15 parts of ore powder, 10-14 parts of fine sand and 7-11 parts of silicate cement. The environment-friendly antique-imitation brick disclosed by the invention has excellent performance in imperviousness, corrosion resistance and freeze-thaw resistance, the compression strength is relatively high, the appearance is pure in color and full in antique tone, and the environment-friendly antique-imitation brick has a realistic effect when the environment-friendly antique-imitation brick is applied to the repair or imitation of antique buildings; meanwhile, by adopting a large amount of industrial and agricultural wastes, the resources are saved, the cost is reduced, the raw materials are readily available, the process is simple, and the environmental hazards are effectively reduced, so that the preparation method disclosed by the invention has a relatively high practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of antique building materials, in particular to an ecological antique bluestone brick and a preparation method thereof. Background technique [0002] In recent years, cement products have been widely used in various fields of construction. However, due to the characteristics of cement in the restoration of ancient buildings, it is not suitable for application in the restoration of ancient buildings. The floor tiles and wall tiles in some ancient buildings have been eroded for many years. The damage was severe. This requires a new type of durable and environmentally friendly antique brick to replace and be used in ancient building restoration projects. The ancient green bricks, also known as blue bricks, are fired from clay. The clay is mixed with water to make adobes, which are calcined in a brick kiln (900°C-1100°C for 8-15 hours) to make bricks. Clay contains iron, and when it is completely oxidized in t...

AI Technical Summary

Problems solved by technology

The existing blue brick production process is more complicated, and the operation is more troublesome, so now the production is relatively small

Moreover, the firing time of existing blue bricks is generally determined according to the size of the kiln; small kilns (about 20,000 to 25,000 blue bricks) generally take 13 days (excluding drinking water) and drinking water usually takes 3 days; large kilns need 25 days about

Based on the above, low output, high cost, waste of energy, etc. restrict the development of green bricks
